Excuse me for quoting poetry, but this scene warrants it.
'The Road goes ever on and on Down from the door where it began. Now far ahead the Road has gone, And I must follow, if I can. Pursuing it with weary feet Until it joins some larger way, Where many paths and errands meet. And wither then? I cannot say.'
(Yes, I'm a 'Lord of the Rings' fanatic. I wrote the above without referring to the book once).
